Kim Jong Un is too smart and has far too much to lose, everything actually, if he acts in a hostile way ... North Korea, under the leadership of Kim Jong Un, has tremendous economic potential, but it must denuclearize as promised.
The official, former nuclear negotiator Kim Yong Chol, says North Korea may resume calling Trump a "dotard.".
